Well, and ETD by itself doesn't know how to do it. The only string 
attributes it can measure are frequency and inharmonicity. To get 
tension (what Jim is looking for) one needs speaking length and 
diameter. The latter is usually stamped on the plate, but the first 
has to be measured with a ruler. Not quite in a ETD's feature set.

I agree, Jim, it would be interesting to see what overall tension 
levels corresponded to in the dimension of tone quality. But before 
that we have to measure tension loads in many pianos. With a ruler. 
After looking for a correspondence, we might realize that tension 
load was but one of the variables/ingredients in the mix.

Evaluating string scales without speaking lengths is kind of like 
discussing key ratio and FW, without reading SW.
